Great sub amp. I have it pushing 3 4ohm 10" subs, Toatal to amp is 1.5ohm and this thing is solid. Not the best amp out there but for the price it rocks. Remote gain knob is nice, works good. Prev amp, JL audio 500 and JL 1000. They are great but over priced, this works just fine. save your $. I would compare it to the JL 500.
